Answer:
3seconds
Explanation:
Time of flight of an object is the time taken by the object to spend in the air before landing. Mathematically it is represented as;
T = 2u/g
Where g is the acceleration due to gravity = 10m/s²
If the vertical velocity component (u) is given as 15m/s, the time of flight will be;
T = 2(15)/10
T = 30/10
T = 3seconds.
Therefore the total time by the ball in the air is 3seconds
